Our Story

Pacific Western Aerostructures, Inc. enjoys a coveted position as one of America's Premier manufacturers of aeronautical structural components & assemblies.



Our manufacturing expertise and abilities are very diverse. In  addition to being expert tool makers, Pacific Western Aerostructures has  a thorough knowledge of all aspects of conventional manufacturing  techniques and utilizes the latest state of the art procedures found  throughout our industry. One of our keys to success is found in the  diverse manufacturing relationships developed over the 56 years we have  served the aviation community. These relationships have allowed us  access to some of the most highly specialized machinery through out our  network of sister companies. Access to this highly specialized machinery  coupled with PW Aero's Expertly Engineered Tooling & Procedures has  allowed us to offer an amazing array of manufacturing support for your  most complex flight components and assemblies.

Some of our capabilities


Precision Machining & Fabrication

All Engineering and Programing are done using the latest version of  Master Cam and Cad Key. We have the ability of reading and translating  most Cad formats such as Solid Works, Catia and Pro-E. 

PW Aero's staff are excellent tool makers. We pride ourselves in  developing and building Form and Draw Tooling for your most complex  solid models.


Hydro Forming, Stretch Forming & Spun Metal Products

We manufacture a wide variety of Hydro Form Tooling for the Metal  Forming Industry. Our abilities to machine complex surfaces from solid  models has enabled us to develop precise "Hydro Form Dies". 

By developing and manufacturing our own tooling, we can help to  control your costs and lead times by not having to depend on an outside  toolmaker to build tools. 


Precision Sheet Metal Fabrication

Our sheet metal fabrication department uses Cad Key Pro Fold for  pre-layout and development. This program actually generates your flat  pattern from your 3 D solid model. By utilizing Pro Fold in conjunction  with our Omax Water Jet, we can create a complex flat pattern in the  shortest lead time. This allows our mechanics to build a complete  fabricated and formed detail for proofing in about the time it use to  take for just the engineering alone.
